Canon filters, Kenko PX1, PX2, and PX3, 58mm diameter. These are items from the Showa retro era. How about it, collectors? I'm sorry, but I don't know the details. I don't think there is any noticeable damage, but these items have been stored at home for a long time, so please purchase them if you understand that they are from that time. - Brand: Canon - Model: Retro - Filter Type: Kenko PX1 58mm - Filter Type: Kenko PX2 58mm - Filter Type: Kenko PX3 58mm
